利:1) 克隆技术可解除那些不能成为母亲的女性的痛苦。
2) 克隆实验的实施促进了遗传学的发展,为“制造”能移植于人体的动物器官开辟了前景。
3) 克隆技术也可用于检测胎儿的遗传缺陷。将受精卵克隆用于检测各种遗传疾病,克隆的胚胎与子宫中发育的胎儿遗传特征完全相同。
4) 克隆技术可用于治疗神经系统的损伤。成年人的神经组织没有再生能力,但干细胞可以修复神经系统损伤。
5) 在体外受精手术中,医生常常需要将多个受精卵植入子宫,以从中筛选一个进入妊娠阶段。但许多女性只能提供一个卵子用于受精。通过克隆可以很好地解决这一问题。这个卵细胞可以克隆成为多个用于受精,从而大大提高妊娠成功率。
弊:1) 克隆将减少遗传变异,通过克隆产生的个体具有同样的遗传基因,同样的疾病敏感性,一种疾病就可以毁灭整个由克隆产生的群体。 可以设想,如果一个国家的牛群都是同一个克隆产物,一种并不严重的病毒就可能毁灭全国的畜牧业。
2) 克隆技术的使用将使人们倾向于大量繁殖现有种群中最有利用价值的个体,而不是按自然规律促进整个种群的优胜劣汰。从这个意义上说,克隆技术干扰了自然进化过程.
3) 克隆技术是一种昂贵的技术,需要大量的金钱和生物专业人士的参与,失败率非常高。多莉就是277次实验唯一的成果。虽然现在发展出了更先进的技术,成功率也只能达到2-3%。
4) 转基因动物提高了疾病传染的风险。例如,如果一头生产药物牛奶的牛感染了病毒,这种病毒就可能通过牛奶感染病人
5) 克隆技术应用于人体将导致对后代遗传性状的人工控制。克隆技术引起争论的核心就是能否允许对发育初期的人类胚胎进行遗传操作。这是很多伦理学家所不能接受的。
6) 克隆技术也可用来创造“超人”,或拥有健壮的体格却智力低下的人。而且,如果克隆技术能够在人类中有效运用,男性也就失去了遗传上的意义。
7) 克隆技术对家庭关系带来的影响也将是巨大的。一个由父亲的DNA克隆生成的孩子可以看作父亲的双胞胎兄弟,只不过延迟了几十年出生而已。很难设想,当一个人发现自己只不过是另外一个人的完全复制品,他(或她)会有什么感受?
所以说,科学技术有时就是一把双刃剑,有利也有没弊,没有标准答案!就看人们这样利用了!

We are talking about the advantages and disadvantages of biotechnology mainly refers to the clone, its advantages and disadvantages of a
Lee: 1) cloning technology are able to remove those who can not become mothers of female suffering.
2) The implementation of cloning experiments for the development of genetics, in order to "create" can be transplanted into the body opened up the prospect of animal organs.
3) cloning technology can also be used to detect fetal genetic defects. The fertilized eggs used to detect a variety of genetic diseases, cloning, cloned embryos and the uterus is identical genetic characteristics of the developing fetus.
4) cloning technology can be used to treat nervous system damage. Adults, there is no regeneration of nerve tissue, but the stem cells can repair nervous system damage.
5) In vitro fertilization procedure, doctors often need more than one fertilized egg implanted in the uterus, in order to filter from one phase into the pregnancy. However, many women can only provide an egg for fertilization. By cloning can solve this problem. The egg can be cloned into a number of for fertilization, thus significantly increasing the pregnancy success rate.
Disadvantages: 1) cloning will reduce the genetic variation generated by cloning the individual has the same genes, the same disease, the sensitivity of a disease that can destroy the entire group generated by cloning. Can imagine that if a country's cattle are the product of the same clone, a virus is not serious could destroy the country's animal husbandry.
2) the use of cloning technology will allow people to tend to the large population of existing populations, most individuals use value, rather than the entire population of the laws of nature to promote survival of the fittest. In this sense, cloning technology interfere with the natural evolutionary process.
3) cloning technology is an expensive technology, requires a lot of money, and biological professionals to participate, failure rate is very high. Dolly is the only 277 experimental results. Although it developed a more advanced technology, the success rate can only reach 2-3%.
4) The transgenic animals increases the risk of disease transmission. For example, if a production of drugs milk cows infected with a virus, the virus may be infected through the milk of patients
5) cloning technology to humans will lead to genetic traits to future generations of artificial control. The core of cloning technology in dispute is whether they can allow for the early development of genetic manipulation of human embryos. This is what many ethicists can not accept.
6) cloning technology can also be used to create a "Superman", or have a robust physique who has mental retardation. Moreover, if cloning techniques can be used effectively in humans, men will lose the genetic significance.
7) The cloning technology on the impact of family relationships will also be enormous. One from the father's DNA cloning of the resulting child can be seen as his father's twin brother, but was delayed for several decades just born. Is hard to imagine that when a person finds himself is just a complete copy of another person, he (or she) will feel?
So, science and technology is a double-edged sword sometimes, there are advantages and no disadvantages, there is no standard answer! To see if people are used in this way!
